Abstract PDF: Objectives
This study examined the changes in dietary habits, the prevalence of chronic diseases, and mental health problems in the regional areas of the Republic of Korea before and after the COVID-19 pandemic to provide evidence of the status of regional health inequalities.
Methods
This study analyzed Korean adults aged 19 or older who participated in the Korea Community Health Survey (n = 686,708) and Consumer Behavior Survey for Foods (n = 19,109) from 2018 to 2020. The participants were classified according to their residence area (Seoul metropolitan area, Metropolitan cities, Provinces); 2018-2019 were defined as before COVID-19, and 2020 as after COVID-19. The dietary behaviors, chronic diseases, and mental health problems were measured using a self-report questionnaire.
Results
After COVID-19, the eating-out usage rate in the Seoul metropolitan area and Provinces decreased compared to before COVID-19 (P < 0.001), and when responding that they eat out, the frequency of eating out with household members in the Seoul metropolitan area increased (P = 0.024). The deliveries/takeout usage rate in the Provinces decreased after COVID-19 compared to before (P < 0.001). After COVID-19, the prevalence of obesity decreased in all regions (P < 0.001), and the prevalence of hypertension increased significantly in the Provinces (P = 0.015). The prevalence of diabetes mellitus increased continuously before and after COVID-19 in all regions (P < 0.002). High-risk subjective stress levels increased significantly in the Seoul metropolitan area (P < 0.001), and sleep duration significantly increased in all regions (P < 0.001). Major depressive disorder was reduced significantly in Metropolitan cities (P = 0.042) and Provinces (P < 0.001).
Conclusions
After the COVID-19 pandemic, the prevalence of chronic diseases and mental health problems showed regional differences along with changes in dietary habits. It is necessary to reflect the regional differences in dietary habits in future policies resolving regional health inequalities.

Association between Eating Alone Patterns and Mental Health Conditions by Region among Korean Adults: Kyung Won Lee, Dayeon Shin; Korean J Community Nutr 2021;26(6):441-454. Published online December 31, 2021; DOI: https://doi.org/10.5720/kjcn.2021.26.6.441

Objectives
This study investigated the association between the frequency and pattern of eating alone and the mental health status according to region in Korean adults.
Methods
The data of 10,040 Korean adults aged ≥ 19 years from the Korea National Health and Nutrition Examination Survey (KNHANES) 2017 and 2019 were used. Participants were divided into 4 groups based on their frequency of eating alone: none (all meals together), 1, 2, and 3 meals/day alone. The regions were divided into urban and rural areas. Mental health status was assessed by stress recognition, depressive symptoms, and suicidal ideation. Multivariable logistic regressions were conducted to estimate the adjusted odds ratios (AORs) with 95% confidence intervals (CIs) on the association of the frequency and pattern of eating alone with poor mental health after controlling for covariates.
Results
Among Korean adults, 74.1% ate more than one meal a day alone. Individuals having 3 meals a day alone tended to be less educated, single, single person households, or living in urban areas (all P < 0.05). In rural areas, those having 3 meals/ day alone had higher odds of stress recognition (AOR: 1.55, 95% CI: 1.02-2.35) than those having all meals together. In urban areas, individuals eating alone 3 times/day had higher odds of stress recognition (AOR: 1.60, 95% CI: 1.31-1.96), depressive symptoms (AOR: 1.61, 95% CI: 1.23-2.12), and suicidal ideation (AOR: 2.14, 95% CI: 1.42-3.22) compared to those having all meals together. Urban residents having dinner alone had higher odds of depressive symptoms (AOR: 1.29, 95% CI: 1.05-1.58) and suicidal ideation (AOR: 1.66, 95% CI: 1.19-2.33) than those having dinner with others.
Conclusions
Our findings showed that the frequency and patterns of eating alone were differentially associated with increased odds of poor mental health according to region of residence. Nutrition education is needed for those frequently eating alone, particularly those living in urban areas, to highlight the advantages of eating together and to ensure that they have balanced and healthy meals even if they eat alone.

OBJECTIVES
This study was performed to investigate the associations of food security with socio-demographic characteristics, nutrient intakes and mental health status among older Korean adults.
METHODS
This study was conducted using data from the 2008-2010 Korea National Health and Nutrition Examination Survey (KNHANES). Subjects were 4,451 adults aged 65~98 years. Food security was measured using a self-reported question on food sufficiency of subjects' household. Based on the answers, study subjects were classified into secure, mildly insecure, moderately insecure, and severely insecure groups. Dietary intake was estimated by 24-hour dietary recall. Nutrient intake was assessed by dietary reference intakes (DRI). As for mental health status, the data on mental stress, depression, and suicide ideation were used.
RESULTS
Rate of food insecurity in older adults was 14.3%. Old age, being female, low education, low income level, living alone, and discomfort in daily living were more related to food insecurity. Means of nutrient intakes were significantly different according to food security status. Intakes of calcium, potassium, and vitamin B2 were lower than recommended intakes in all groups. Consumption amounts of soy and soybean products, vegetables, mushrooms, fruits, vegetable oils, meats, eggs, seafood, and dairy products were lower in food insecure groups. Mental stress, depression, and suicide ideation were higher in food insecure groups independent of the gender and income level.
CONCLUSIONS
These present findings suggested that food security is related to mental health as well as nutrition status in older Korean adults. A national system that include food and psychosocial support programs for the elderly should be considered in order to improve the overall health of older Korean adults.

Effect of Eating with Family or Alone on the Self-rated Mental or Physical Health: The Elementary School Children in Daejeon Area: Soon Jung Sung, Sunja Kwon; Korean J Community Nutr 2010;15(2):206-226. Published online April 30, 2010

Abstract PDF: The purpose of this study was to examine the effect of eating with family or alone on the self-rated mental or physical health and then work out strategies of making people recognize the importance of eating with family and its practice. Study subjects were 610 primary school 5th- and 6th-grade students in Daejeon Area. A questionnaire survey was carried out. 57.9% of students had working mothers. The frequency of meal in a day was 2.90 +/- 0.42 and this frequency was lower in students who had working mothers (p < 0.05). The frequency of skipping breakfast (times/week) was 1.02 +/- 1.77. The frequencies of eating alone (times/week) were 1.04 +/- 1.65 for breakfast and 0.97 +/- 1.52 for dinner. Also, the frequency of eating alone for dinner was higher in students who had working mothers (p < 0.001). When the frequency of eating alone for breakfast or dinner was higher, the frequencies of skipping breakfast and dinner were also higher (for all, p < 0.01). When the frequency of eating alone for breakfast or dinner was higher, the self-rated positive mental health were lower (p < 0.05 and p < 0.01 respectively) and the self-rated negative mental health (for dinner, p < 0.05) and the self-rated negative physical health was higher (p < 0.05 and p < 0.01 respectively), thus presenting negative health. The frequencies of eating with family (times/week) were 3.37 +/- 2.50 for breakfast and 4.14 +/- 2.19 for dinner. Also, the frequency of eating with family for dinner was lower in students who had working mothers (p < 0.01). When the frequency of eating with family for breakfast was higher, the frequency of skipping breakfast was lower (p < 0.01). When the frequency of eating with family for dinner was higher, the frequency of skipping dinner was lower (p < 0.01). In addition, when the frequency of eating with family for breakfast or dinner was higher, the self-rated positive mental health were higher (for both, p < 0.01) and the self-rated negative mental health was lower (for breakfast, p < 0.01) and self-rated negative physical health were lower (for both, p < 0.01), thus presenting positive health. Therefore, in order to maintain positive health, it is necessary to recognize the importance of eating with family at home and educate people to carry out a systematic and continuous dietary life, thus increasing eating with family and reducing eating alone and skipping a meal.

The Interrelations among Nutrition Education, Satisfaction with School Lunch, School Lunch Leftovers and Self-rated Mental or Physical Health: The Elementary School Children in Daejeon Area: Sunja Kwon, Soon Jung Sung, Sun Yung Ly; Korean J Community Nutr 2010;15(1):94-107. Published online February 28, 2010

Abstract PDF: The purpose of this study was to examine the interrelations among current status of nutrition education, satisfaction with school lunch, school lunch leftovers and self-rated mental or physical health in order to find out the effective method of nutrition education. For this, a questionnaire survey of 623 primary school 5th and 6th-graders in Daejeon area was carried out. The eating places were classrooms (41.1%) and restaurants (58.9%). A 59.2% of students have received nutrition education and the opportunity of receiving nutrition education was more in 5th-graders than in 6th-graders (p < 0.001). The score of nutrition knowledge was 9.4 +/- 2.8 out of 15. When the score of nutrition knowledge was higher, the practical use of nutrition knowledge was higher (r = 0.134, p < 0.01); the score of school lunch leftovers were less (r = -0.116, p < 0.01); and the score of self-rated mental health was more positive (r = 0.198, p < 0.01). The practical use of nutrition knowledge was 2.9 +/- 1.1 out of 5. When the practical use of nutrition knowledge was higher, satisfaction with school lunch was higher (r = 0.105, p < 0.01); school lunch leftovers were less (r = -0.103, p < 0.01); the score of self-rated positive mental health was higher (r = 0.293, p < 0.01); and the scores of self-rated negative mental health (r = -0.119, p < 0.05) and physical health (r = -0.126, p < 0.01) were lower, thus rating their health more positively. The score of satisfaction with school lunch was 3.4 +/- 1.0 out of 5. When the satisfaction with school lunch was higher, the score of school lunch leftovers was less (r = -0.216, p < 0.01); the score of self-rated positive mental health was higher (r = 0.147, p < 0.01); and the score of self-rated negative health was lower (r = -0.121, p < 0.01). The score of school lunch leftovers was 2.9 +/- 1.4 out of 5. When the school lunch leftovers were less, self-rated positive mental health was significantly higher (r = -0.146, p < 0.01); and the scores of self-rated negative mental health (r = 0.135, p < 0.01) and physical health (r = 0.223, p < 0.01) were significantly lower, thus presenting positive health. Therefore, in order to maintain positive health condition, it is necessary to carry out nutrition education, which is able to raise the nutrition knowledge and practical use of nutrition knowledge, school lunch satisfaction and to reduce the school lunch leftovers.
